| blue-green color and composition of stejneger's beaked whale (mesoplodon stejnegeri) milk. | two hundred ml of milk were obtained from a lactating stejneger's beaked whale stranded at ninilchik, alaska on 21 oct, 1980. total solids (41%) were similar to values reported for sperm and belukha whales, while fat (17%) was half as great and crude protein (17%) was 2-4 times greater than in milk of these species. lactose was not detected. calcium (0.22%) was greater than reported for pigmy sperm whales but less than for blue whales. phosphorus (0.07%) was less than for any of the above specie ... | 1984 | 6509923 |
| polychlorinated biphenyls and their hydroxylated metabolites (oh-pcbs) in the blood of toothed and baleen whales stranded along japanese coastal waters. | in this study, we determined the residue levels and patterns of polychlorinated biphenyls (pcbs) and hydroxylated pcbs (oh-pcbs) in the blood from eight species of toothed whales and three species of baleen whales stranded along the japanese coast during 1999-2007. penta- through hepta-chlorinated pcb congeners were the dominant homologue groups in all cetaceans. in contrast, specific differences in the distribution of dominant oh-pcb isomers and homologues were found among the cetacean species. ... | 2010 | 20426459 |
| molecular identification of novel alpha- and gammaherpesviruses from cetaceans stranded on japanese coasts. | herpesviral infections have been documented in some cetaceans; however, they have not yet been identified in species in the western north pacific. in the present study, 178 tissue samples from 76 stranded cetacean individuals were tested for the presence of herpesviruses. herpesvirus genomic dna fragments surrounding the dna polymerase gene were amplified in samples from four individuals. ta cloning and direct sequencing of these dna fragments revealed the presence of two novel alphaherpesviruse ... | 2011 | 21303205 |
| cdna-derived amino acid sequences of myoglobins from nine species of whales and dolphins. | we determined the myoglobin (mb) cdna sequences of nine cetaceans, of which six are the first reports of mb sequences: sei whale (balaenoptera borealis), bryde's whale (balaenoptera edeni), pygmy sperm whale (kogia breviceps), stejneger's beaked whale (mesoplodon stejnegeri), longman's beaked whale (indopacetus pacificus), and melon-headed whale (peponocephala electra), and three confirm the previously determined chemical amino acid sequences: sperm whale (physeter macrocephalus), common minke w ... | 2006 | 16962803 |
| amyloidosis in two stejneger's beaked whales (mesoplodon stejnegeri) stranded at the sea of japan. | amyloidosis is a disease characterized by the tissue deposition of autologous extracellular fibrillar proteins that can result in compression of adjacent tissues. amyloidosis is well-recognized in a wide variety of animals, including mammals, birds, and reptiles. however, to date, there is only one report of amyloidosis in cetaceans. during 1999 and 2000, among 12 stejneger's beaked whales (mesoplodon stejnegeri) that were stranded along the sea of japan's coast, amyloidosis was found in two wha ... | 2007 | 17469284 |
| toxic identification and evaluation of androgen receptor antagonistic activities in acid-treated liver extracts of high-trophic level wild animals from japan. | sulfuric acid-treated liver extracts of representative high-trophic level japanese animals were analyzed by toxic identification and evaluation (tie) with chemically activated luciferase expression (calux) and chemical analysis to elucidate androgen receptor (ar) antagonistic activities and potential contributions of organochlorine pesticides (ocps) and polychlorinated biphenyls (pcbs). the activities were detected in striped dolphins (n = 5), stejneger's beaked whales (n = 6), golden eagle (n = ... | 2015 | 26321157 |
| pathological findings and probable causes of the death of stejneger's beaked whales (mesoplodon stejnegeri) stranded in japan from 1999 and 2011. | one hundred and twenty stranding events of stejneger's beaked whales were reported in japan between 1999 and 2011. the purpose of this study is to introduce pathological data and to discuss probable causes of death for 44 stejneger's beaked whales among them. the significant pathological findings were the pulmonary edema, parasitic granulomatous nephritis, emaciation, amyloidosis, suppurative bronchopneumonia and so on. the probable causes of death were categorized as noninfectious in 43 of the ... | 2015 | 25328004 |
| spatio-temporal patterns of beaked whale echolocation signals in the north pacific. | at least ten species of beaked whales inhabit the north pacific, but little is known about their abundance, ecology, and behavior, as they are elusive and difficult to distinguish visually at sea. six of these species produce known species-specific frequency modulated (fm) echolocation pulses: baird's, blainville's, cuvier's, deraniyagala's, longman's, and stejneger's beaked whales. additionally, one described fm pulse (bwc) from cross seamount, hawai'i, and three unknown fm pulse types (bw40, b ... | 2014 | 24465877 |
| morphology of the tongue in a newborn stejneger's beaked whale (mesoplodon stejnegeri). | this light and scanning electron microscopic (sem) study on the tongue of a newborn stejneger's beaked whale (mesoplodon stejnegeri) demonstrated a clear difference in its form from than that of other cetacean and adult stejneger's beaked whales. this newborn stejneger's beaked whale had a spoon-like shaped tongue. the dorsal surface in the center part of the tongue was flat and did not have papillae, but there were marginal papillae and small papillae on the anterior part of the tongue. in the ... | 2008 | 18464527 |
